The light novel 'Re:Zero - Starting Life in Another World' also fits this. Subaru is a normal boy who is suddenly thrown into a fantasy world. At first, he is completely out of his depth, but through countless deaths and resurrections, he learns, grows, and slowly becomes a hero - like figure who can save others. His journey from being a zero in this new world to a hero is full of hardships and character development.
Hard to say exactly. The Re:Zero anime covers a substantial part of the novels, but the specific number is hard to determine as it depends on how the content was adapted and which parts were prioritized for the anime.
Well, it's not straightforward to give an exact number. The anime might selectively adapt certain parts of the light novels, and the count can change based on the production decisions.
Sashi is also a main character. She is Penn's friend and often helps him during his adventures. She is very smart and resourceful, coming up with great ideas to solve problems.
The My Hero Academia anime is quite faithful to the manga. It captures the main events and character traits well. However, there are some minor differences to accommodate the medium of animation and to keep things interesting for viewers.
